摘　　要：本文用理论分析和试验研究证实了混杂复合材料构成的软化带可用以控制碳/环层板中的裂纹扩展,以较小的重量代价,提高其剩余强度。文章还分析了裂纹尺寸和软化带的材料、参数对碳/环层压板的损伤容限特性的影响。This paper presents a softening strip design of hybrid composite material. It is proved by means of theoretical analysis and experimental investigation that the softening strip can be used to prevent the crack propagation and to increase the residual strength of graphite/epoxy laminated composite plate. The influence of the crack size and the paramen-ters of the softening strips on the damage tolerance capability are also analysed.
